Convert Java List to Scala Seq

Question

I need to implement a method that returns a Scala Seq, in Java.

But I encounter this error:

java.util.ArrayList cannot be cast to scala.         


        

Answer 1

JavaConverters is what I needed to solve this.

import scala.collection.JavaConverters;

public Seq convertListToSeq(List inputList) {
    return JavaConverters.asScalaIteratorConverter(inputList.iterator()).asScala().toSeq();
}
